Yall apparently the “It’ll force your body to become aroused” line isn’t really referring to Changdeok but to Jongwu. He’s saying that if he drinks Changdeok’s blood he (Jongwu) might get too excited ykyk and he’s asking Changdeok if he’s ok with that.
This is all from posts I’ve seen on twt, I personally don’t know any Korean myself. I just wanted to share what I’ve seen ヾ(☆▽☆)
